The rate of the beta decay of neutral kaons is calculated within the meson dominance approach taking into account the relation between the KKρand ππρcoupling constants which follows from the vector meson dominance in electromagnetic interactions and isospin symmetry. The decay rate transforms into the following branching fraction summed over the charge states indicated: B(K0L -> K+- e-+ nu)=(2.53+-0.10)x10-9. The error is dominated by our estimate of isospin violating effects. Experimental aspects of such a measurement are discussed.
